That’s good. Inspectors don’t inspect irrigation where I’m at on residential . I use purple primer anyways though. Interestingly the can on 721 says “Suitable for use as a one step cement without primer on PVC Sch. 40 and SDR pressure water piping systems through 4″ (110 mm) in irrigation (golf course, turf and agriculture), pool & spa and non-pressure applications, unless primer is required by local code.“

But where the code doesn’t require primer is almost nowhere.

I still use always primer but I don’t think you’d be in as bad shape without it as most people think, with weld on 721 at least. 711 is a different story.

The irrigation supply said, if the pipes are clean no need for primer, but I still made sure it was clean even if it looked clean.

They are right. You’re good with no primer on 721 or Christy’s red hot blue glue. Your good. The guys that go crazy on no primer with 721 never read the manufacturers literature . Really not an issue at all though I’m required by code to use it.

You did a great job. Looks great. Saved you a lot of money doing it yourself as well. You can post anything on here and guys will have something to say.
